基于逆向工程的创新设计与3D打印技术的实践教学

Practical teaching of innovative design and 3D printing technology based on reverse engineering

结合国家职业技能大赛竞赛内容和新职业中增材制造设备操作员的岗位需求,设计了六大实践教学任务:模型三维数据采集、模型数据处理、逆向建模、产品创新设计、产品3D打印及后处理、产品精度检测,以飞机模型的创新设计为案例对实践教学进行了说明。该教学实践的开展,让学生掌握了常见3D打印设备的使用方法,理解了逆向工程在创新设计中的用途,对提升学生的创新能力、设计能力和岗位竞争力有促进作用。

Based on the content of the national vocational skills competition and the job require-ments of additive manufacturing equipment operators in new occupations,six practical teaching tasks were designed,include model 3D data acquisition,model data processing,reverse modeling,product innovation design,product 3D printing and post-processing,and product accuracy detec-tion.The practical teaching was explained by taking the innovative design of aircraft model as an example.The implementation of the teaching practice enabled students to master the usage of common 3D printing equipment and understand the use of reverse engineering in innovative de-sign,which played an important role in promoting students'innovation ability,design ability and job competitiveness.
